Sign: Secure eSignatures
Proof's Sign is an eSignature platform that integrates identity verification directly into the signing process, offering customizable verification levels, automated compliance with over 4.5 million rules, native unification of identity and signing to reduce vendor complexity, control over signing order, stakeholder visibility without edit access, seamless API integration with existing systems, and upcoming cryptographically verified digital signatures for tamper-proof evidence.
Signatures you can trust
Get your documents signed in minutes. You can pick the level of verification for every signature and get an audit trail automatically. Identity verification isn’t a separate task—it's just part of the signing flow.
Proof of identity, not just proof of a click
Proof’s Sign gives you eSignature with a critical advantage: the ability to put identity verification in front of the signing event. Dial up or down the rigor based on the document's risk level—no switching platforms, no stitching together vendors.
Streamlined workflows
Proof enforces the notarial and underwriter requirements, so every closing is compliant by default. More than 4.5M automated rules run behind every transaction.
Stop stitching eSign vendors to an IDV tool
With Proof, identity and signing are natively unified—fewer vendors, fewer failure points, a smoother customer experience.
Digital signatures
Coming soon
Most platforms give you electronic signatures—a click, a typed name, a checkbox. With Sign, you get cryptographically verified identities and tamper-proof evidence.
Everything eSignatures should be
Proof has full feature parity with the eSign tools you've used before—plus built-in identity verification that legacy vendors have never been able to match.
Control who signs first
Ensure documents are signed in the right order. Set a sequence so each recipient is only notified when it’s their turn to sign, keeping your workflow and audit trail organized.
Keep the right people in the loop
Add stakeholders who need visibility without giving them edit or signing access. CC'd contacts receive a copy of the completed document automatically.
Integrate seamlessly
Our API lets you initiate document sends directly from your CRM, LOS, or any internal platform—so signing happens inside the process your team already uses, not as a separate step outside it.
Every signer signs their way
Proof supports mixed signing workflows—one signer can complete their portion electronically while another completes a notarization.
Control the verification bar
Set identity requirements per document type. Low-risk forms can use lightweight checks. High-stakes agreements can require ID verification or biometric match.
Tag once. Send to thousands.
Create a document template with all your fields, signature flags, and verification requirements set up once. Then send it to as many signers as you need—individually or in bulk.
“Our clients don’t want to print, scan, or drive across town just to initial one page. With Proof, they can sign everything securely from wherever they are—and we can move on with the closing.”
